Using XIAO-ESP32-C3

Download Arduino IDE from here.


Navigate here:


Paste "https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json" into the shown location.


Navigate to the boards manager tab and download esp32 by Espressif Systems.


LED Blink

I'll first create code for blinking an LED.


Wrote this code for blinking the LED.

I later realized that I accidentally put ":" instead of ";" in some places. If you're writing this code, just replace the ":" with ";".


Connected the XIAO-ESP32-C3 to my computer.


Clicked here to connect the IDE to the board.


Selected the board and the port.


Changed the code because the legs of the LED wasn't long enough.
